This rocks the tot; gli

level' 16 to the rear and advances the lin earrying .with it -the slide valve 7. This serves to admit steam or air from the inlet 30 to the rear of the cylinder and places the forward end of the cylinder in' communiontion with the outlet 31 whereupon the piston 3 is advanced, carrying with it the cross head 5 and lever 10, which movement continues until therockingofthe lastnamed lever about the fulcrum 13 restores the slide valve to closed position -whichnormally o ecurs when the piston reaches a point .in `the cylinderconesponding to the setting` of the lever 2l upon its' sector.. Normally, the iston moves through a distance three or our times greater than'the movement of the lever relatively-toits sector; thus if the notches in the sector are-one eighth ineh'wfide and the teeth are 'one eighth in width, the smallest Ypossible movement of the lever is one quartor inch, which corresponds to the movement of the piston of one and.v one-half to two inches, supposing the device to be' in perfect. adjustment; while if the pivots are worn or the valve displaced, or the packings leaky, the piston frequently 'moves a distance varying as much as fifty per cent. more or less than normal.

In order to overcome this diiculty and l to provide for-4i vmore, accurate adjustment, vl' substitute for one of the pivots in'sidethe cab a device including an eccentric part tolgather with means for rotating the' part sov that,.without disengagin-gr the'lever from the sector, the reach rod Acan be 'shifted through any distance less than that which would correspond to a .movement oi' the lever betweenvadjaeent notches of the sector. This device can vbe applied' either 'to th'epivot' botweenfthe lever and reach rod or to that between the'lever and the sector and may be made; in any one severalways.
